This is a java applet showing a simple resistive circuit.  The green
color indicates positive <a href="http://en.wikipedia.org/wiki/Voltage">voltage</a>,
and the gray color indicates
<a
   href="http://en.wikipedia.org/wiki/Ground_%28electricity%29">ground
   (or earth)</a>.  The movement of yellow dots
indicates <a
   href="http://en.wikipedia.org/wiki/Electric_current">current</a>
   (in the <a href="http://en.wikipedia.org/wiki/Electric_current#Conventional_current">conventional direction</a>).  The
left side of the circuit shows a voltage
source providing 5 volts, and the current flows through a number of
switches and resistors to the right.  The amount of resistance in ohms
is shown to the right of each <a href="http://en.wikipedia.org/wiki/Resistor">resistor</a>.
<p>
To turn a switch on or off, just click on it.  If you move the mouse over any
component of the circuit, you
will see a short description of that component and its current state in the
lower right corner of the window.
<p>
If there is only one switch closed on top and one closed on the
bottom, then there is a single path through the circuit,
and by <a href="http://en.wikipedia.org/wiki/Ohm's_law">Ohm's Law</a>,
the current will be equal to 5V divided by the total resistance
through the current path.
<p>
If there are multiple current paths, you may
have <a
	href="http://en.wikipedia.org/wiki/Series_and_parallel_circuits#Resistors_2">resistors
    in parallel</a>.
